+# Fixed Vercel Deployment Issues
+
+## Issues Resolved
+
+### 1. Build and Linting Errors ✅
+- Fixed ESLint configuration for Node.js environment
+- Resolved React component syntax errors 
+- Fixed CSS @import placement issues
+- Cleaned up unused variables and imports
+
+### 2. API URL Configuration ✅
+- Created configurable API URL system (`src/lib/config.js`)
+- Replaced all hardcoded `localhost:3001` references
+- Added `VITE_API_URL` environment variable to `vercel.json`
+
+### 3. API Server Structure ✅
+- Updated API server to export for Vercel compatibility
+- Fixed environment variable loading for production
+- Updated CORS to include production domains
+
+## Deployment Instructions
+
+### Frontend Deployment (Vercel)
+1. Connect your GitHub repository to Vercel
+2. Set these environment variables in Vercel Dashboard:
+   ```
+   VITE_SUPABASE_URL=https://your-project.supabase.co
+   VITE_SUPABASE_ANON_KEY=your-supabase-anon-key
+   VITE_STRIPE_PUBLISHABLE_KEY=your-stripe-publishable-key
+   VITE_API_URL=https://your-api-domain.vercel.app
+   ```
+3. Deploy with these settings:
+   - Framework: React (Vite)
+   - Build command: `npm run build`
+   - Output directory: `dist`
+
+### API Deployment (Separate Vercel Project)
+1. Create a new Vercel project for the `/api` folder
+2. Set these environment variables:
+   ```
+   OPENAI_API_KEY=your-openai-key
+   VITE_SUPABASE_URL=https://your-project.supabase.co
+   SUPABASE_SERVICE_ROLE_KEY=your-service-role-key
+   STRIPE_SECRET_KEY=your-stripe-secret
+   STRIPE_WEBHOOK_SECRET=your-webhook-secret
+   STRIPE_CREATOR_PRICE_ID=your-creator-price-id
+   STRIPE_PRO_PRICE_ID=your-pro-price-id
+   FRONTEND_URL=https://your-frontend-domain.vercel.app
+   NODE_ENV=production
+   ```
+
+### Important Notes
+- The API and frontend must be deployed as **separate Vercel projects**
+- Update the `VITE_API_URL` to point to your deployed API domain
+- The build now completes successfully without errors
+- All environment variables are properly configured in `vercel.json`
+
+## Test Your Deployment
+1. Build locally: `npm run build` (should complete without errors)
+2. Deploy frontend to Vercel
+3. Deploy API to Vercel (separate project)
+4. Update environment variables with actual values
+5. Test the application functionality
